Springfield 1911 Ronin AOS 45ACP 4.25" 8+1 Vault

The Springfield Armory 1911 Ronin AOS 4.25" .45 ACP is the Commander-size 1911 perfected for the modern era: timeless two-tone beauty meets factory-direct red-dot capability in a package that carries like a dream and hits like thunder. A forged aluminum alloy frame keeps weight to a featherlight 30 ounces, while the 4.25" match-grade, fully supported hammer-forged barrel and bushing deliver full-house .45 ACP performance through 8+1 rounds. The iconic hot-salt blued slide rides over a polished stainless frame, crowned with genuine Crossed Cannon double-diamond laminate wood grips that look heirloom-grade and feel locked-in all day long.

Springfield's Agency Optic System (AOS) sets it apart: the slide is precision-milled at the factory with interchangeable plates that direct-mount today's top micro red dots (RMR, RMSc, DeltaPoint Pro, Docter, etc.) with zero extra hardware. Every plate integrates a serrated black rear sight at perfect co-witness height, paired with a blazing fiber-optic front for instant acquisition. Add a crisp 4.5-5 lb GI-style trigger, extended beavertail, and flawless Gen2 Speed trigger, and you have a pistol that shoots like a custom shop build the moment you pick it up.

This is a factory "Vault" Ronin AOS: hand-selected by Springfield as a flawless trade-show and display example, never sold at retail, never fired beyond proof, and preserved in pristine, unfired condition. The Springfield 1911 Ronin AOS is still covered by the lifetime warranty. For the carrier who demands classic 1911 soul with 21st-century speed, the competitor chasing style points, or the collector hunting the ultimate two-tone optic-ready Commander, this untouched Vault pistol is the one: heirloom aesthetics, cutting-edge performance, ready to carry today and treasure forever.

*Note: This is a "Vault" model, which is a representative/sample and trade‑show display firearm. This firearm carries Springfield's full warranty.*
